Only briefly, I've enjoyed it so far, played just enough to try out the new hero, and I thought it was quite good, about to give endless mode as the new hero a try. :)
I really do like just how different the different characters feel to play as, I'd love to see even more to come.
With the codex, it would be cool to also have the final end state of the map saved with the stats, although that may be slighly hard. :)
